` Patented July 5, 1938 UNITED STATES PATENT OFFiE COOKING STOVE` BURNER ATTACHMENT FOR HEATING WATER 2 Claims.

The object of my invention is to provide a device which can be used on an oil stove or a gas stove whereby waste heat from the burner may be utilized in heating water at the same time the stove is being used for cooking purposes.

I attain these and other objects of my invention by the mechanism illustrated in the accompanying drawing, in which:

Figure 1 is a view of my invention partly in elelU vation and partly in diagram;

Fig. 2 is a top plan view of the heating pipes and supporting frames over one of the burners of the stove;

Fig. 3 is a detail sectional View on line 3 3 of l5 Fig. 2;

Like numerals designate like parts in each of the views.

Referring to the accompanying drawing there is illustrated a hot water tank l having the usual no Cold water pipe 2 and hot water pipe 3, drain pipe 6 and valve l" in the drain pipe. I provide a pipe 4 opening out of the bottom of the tank and a pipe 5 opening in to the top of the tank each controlled by a suitable cut-oli valve 1. The pipe 5 4 connects with the lower end of the hot water heating tank with the hot water heating set of pipes over the burner at one end of the stove and the pipe 5 connects with the hot water heating set of pipes over the burner at the other end 30 of the stove. The set of heating pipes over each burner is designated 9 and they are connected by connecting pipes lll as indicated diagrammatically in Fig 1. The pipes 9 rest in depressions Il in the metal supporting frame 8 which has reinforcing bars 8a and I2 to complete the frame structure, as shown in Fig. 2. The braces 8a and I2 also serve as a rest or support for pans, kettles or other utensils. By reason of the provision of the depressions Il in the bars 8, the outer surface of the set of pipes 9 through which the Water circulates is aligned with the upper surface of the bars 8, 8a and I2, so as to provide a level surface for supporting pans, kettles or cooking utensils. The dot and dash circle in Fig. 45 2 of the drawing indicates the approximate size of the usual burner of a gas or oil stove, and it will be noted that four lines of water pipes will receive heat at the same time from this burner. The frame and water pipes as shown in Figs. 2 and 1 will replace the usual cast iron frame that 5 comes with gas or oil stoves.

While the construction for a three burner stove is shown in Fig. 1 of the drawing, it is in the contemplation of my invention to make a device that will be adaptable for use on a standard 10 four burner stove or for any number of burners desired.

What I claim is:

1. In a cooking stove burner attachment for heating water having a set of connected water heating pipes of suitable size to come within the range of the flame of the burner of a gas or oil cooking stove, a metal frame of suitable size to replace the usual stove frame and functioning as a supporting means for the aforesaid set of water heating pipes, said frame having depressed portions in its bars to receive the water heating pipes whereby the upper surface of the water heating pipes and of the frame will be on a level and in the same plane, whereby cooking receptacles placed over the burner will be level.

2. In a cooking stove burner attachment for heating water comprising a plurality of like sets of connected water heating pipes of suitable size to come within the range of a plurality of burners of a gas or oil cooking stove, said sets or pipes being connected to each other and each of the end sets of pipes being connected with a hot water tank, and Valves in the pipes leading from one 4set of heating pipes to the next setoof heating 35 pipes, a metal frame of suitable size to replace the usual stove frame and functioning as a supporting means for the aforesaid sets of water heating pipes, said frame having depressed portions in its bars to receive the water heating pipes whereby the upper surface of the water heating pipes and of the frame will be on a level and in the same plane, whereby cooking receptacles placed over the burner will be level.
